You found an organic compound containing chiral carbon atom with the following four substituents: HC≡C-,Cl-,O=C- and H₂C=CH-.What would be the correct order of their priorities?

Question

Quizplus · Accepted Answer

The priority of the substituents is determined by the atomic number of the first atom in each group. In this case, the priorities are as follows: 1) O=C- (oxygen has a higher atomic number than chlorine) 2) Cl- (chlorine has a higher atomic number than carbon) 3) HC≡C- (carbon has a higher atomic number than sulfur) 4) H₂C=CH- (sulfur has a lower atomic number than carbon, and this substituent has a lower priority than HC≡C- because the carbon in HC≡C- is triple bonded to another carbon, while the carbon in H₂C=CH- is only double bonded to another carbon)
